Contact list availability prioritization

ABSTRACT

A method for contact list prioritization according to predicted reachability includes loading a contact list of contacts and retrieving a reachability value for each corresponding contact in the contact list that has been computed for each corresponding contact according to usage data of each corresponding contact for an associated mobile telephone. Thereafter, contacts in the contact list that are determined to be most reachable according to a corresponding reachability value are displayed first.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to contact list management for mobilecontacts and more particularly to contact list management according toprospective contact reachability.

2. Description of the Related Art

The address book has remained part and parcel of mobile telephony sincethe inception of the cellular network. The address book of a mobilephone is a data store of contacts including names and telephone numbersof those known to the possessor of the mobile phone. Often referred toas a contact list, mobile phones traditionally provide both a generallist of contacts and also a “speed dial” list of most frequentlyaccessed contacts. More advanced smart phones additionally provide thecapability to filter contacts in a contact list, for example in order ofmost frequently contacted or most recently contacted.

Oftentimes, different contacts in a list fulfill an interchangeable rolesuch that when one contact of a role is to be reached telephonically, inthe event that the contact of the role cannot be reached, reaching analternative contact of the same role can be a satisfactory outcome. Atpresent, the manner in which contacts of a role can be reached is besttermed a brute force method. Specifically, one typically begins with anattempt to telephone a first contact of the role and continues throughthe list until a contact of the role is reached. To the extent that thefirst or second contact can be reached, the brute force method cansuffice. However, where the first available and reachable contact of arole resides four or more entries deep in a contact list filtered byrole, the manually intensive brute force method can be extraordinarilywasteful.

The buddy list is a form of contact list common in the instant messengerspace in which a list of contacts can be grouped together in a list ofmost frequently accessed contacts. Further, the availability andreachability of the contacts in the buddy list can be computed centrallyand reported to the buddy list. Typically, the availability andreachability of a contact is determined either manually by the contact,or programmatically by detecting computing activity by the contact. The“presence awareness” of the contacts in the buddy list in turn can beconveyed to the end user visually through icons of different shapes andcolors. In this way, the end user can readily identify when a contact inthe buddy list is available to engage in an instant messaging session.

BRIEF SUMMARY OF THE INVENTION

Embodiments of the present invention address deficiencies of the art inrespect to contact list management and provide a novel and non-obviousmethod, system and computer program product for contact listprioritization according to predicted reachability. In an embodiment ofthe invention, a method for contact list prioritization according topredicted reachability is provided. The method includes loading acontact list of contacts in memory of a host computer and retrieving areachability value for each corresponding contact in the contact listthat has been computed for each corresponding contact according to usagedata of each corresponding contact for an associated mobile telephone.Thereafter, ones of the contacts in the contact list that are determinedto be most reachable according to a corresponding reachability value aredisplayed first.

In one aspect of the embodiment, the usage data for the associatedmobile telephone is based upon accelerometer data of the associatedmobile telephone. In another aspect of the embodiment, the usage datafor the associated mobile telephone is based upon recency or frequencyof use of the mobile telephone to place telephone calls. In yet anotheraspect of the embodiment, the usage data for the associated mobiletelephone is based upon recency or frequency of use of a messagingapplication executing in the associated mobile telephone. Finally, ineven yet another aspect of the embodiment, the usage data for theassociated mobile telephone is based upon recency or frequency ofposting content to a social network through the associated mobiletelephone.

Of note, the contacts in the contact list can be organized according toa common role for the contacts. As such, a directive can be received todial a contact of the common role most likely to be reached. In responseto receiving such a directive, the reachability values for each of thecontacts of the common role can be computed and a contact of the commonrole determined most likely to be reachable can be dialed. In the eventthat a telephone call cannot be completed with the contact of the commonrole determined most likely to be reachable, a contact of the commonrole determined to be next most likely to be reached can be dialed. Theprocess can repeat until such time as a telephone call can be completedto a contact of the common role, or until no contacts of the common roleremain to be dialed.

In another embodiment of the invention, a data processing system can beconfigured for contact list prioritization according to predictedreachability. The system can include a mobile telephone and a hostcomputer with at least one processor and memory disposed within themobile telephone. The system additionally, can include a contact listmanagement module executing in the memory of the host computer. Themodule can include program code enabled to load a contact list ofcontacts in memory of the host computer in the mobile telephone, toretrieve a reachability value for each corresponding contact in thecontact list that has been computed for each corresponding contactaccording to usage data of each corresponding contact for an associatedmobile telephone, and to display in a display of the mobile telephoneones of the contacts first in the contact list that are determined to bemost reachable according to a corresponding reachability value.

The accompanying drawings, which are incorporated in and constitute partof this specification, illustrate embodiments of the invention andtogether with the description, serve to explain the principles of theinvention. The embodiments illustrated herein are presently preferred,it being understood, however, that the invention is not limited to theprecise arrangements and instrumentalities shown, wherein:

FIG. 1 is a pictorial illustration of a process for contact listprioritization according to predicted reachability;

FIG. 2 is a schematic illustration of a data processing systemconfigured for contact list prioritization according to predictedreachability; and,

FIG. 3 is a flow chart illustrating a process for contact listprioritization according to predicted reachability.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention provide for contact list prioritizationaccording to predicted reachability. In accordance with an embodiment ofthe invention, different mobile phones in a cellular network can trackusage data of the mobile phone and the usage data can be processed intoa reachability value. The reachability value in turn can be provided tothe cellular network and consumed by different contact lists of othermobile phones in the cellular network in order to rank contacts in thecontact lists in order to sort the ranked contacts according to likelyreachability. In this way, a mobile phone user seeking to contact aperson in the contact list can select a person most likely to bereached.

In further illustration, FIG. 1 pictorially shows a process for contactlist prioritization according to predicted reachability. As shown inFIG. 1, a mobile telephone 110 can be configured with contact listmanagement logic 120. The logic 120 can compute the reachability of aperson associated with the mobile telephone 110 by computing areachability value 140 from use data 130 of the mobile telephone 110such as accelerometer data, last time of use data or frequency of usedata, messaging data, or social media data. Thereafter, the reachabilityvalue 140 can be provided to contact list management logic 120 in adifferent mobile telephone 110 with which the logic 120 can sortcontacts in a contact list 150 according to the reachability value 140.Further, each contact in the contact list 150 can include a reachabilityicon 160 indicating a reachability of the contact according to thereachability value 140 for a mobile telephone 110 of the contact.

Of note, the reachability value 140 can be computed so as to provide anumerical indication of the contemporaneous reachability of a contactbased upon use data 130 of a corresponding mobile telephone 110. Forexample, the use data 130 can include accelerometer data of the mobiletelephone 110 indicating the movement of a contact holding the mobiletelephone 110, time of use data indicating that the mobile telephone iseither frequently used, or more recently used, messaging data indicatingthat the contact had transmitted messages using a messaging applicationin the mobile telephone 110, or social media data indicating that thecontact through the mobile telephone 110 had posted contact to a socialnetwork. The reachability value 140 can be computed within the mobiletelephone 110 and transmitted to other mobile telephones 110 or to acentral server, or the use data 130 can be transmitted to other mobiletelephones 110 or to a central server from which the reachability value140 can be computed.

The process illustrated in connection with FIG. 1 can be implementedwithin a data processing system configured for cellular telephony. Inyet further illustration, FIG. 2 schematically shows a data processingsystem configured for contact list prioritization according to predictedreachability. The system can include a mobile telephone 210 includingcellular telephone circuitry 220 and also a host computer 230. The hostcomputer 230 can include one or more processors 230A, memory 20B, fixedstorage 230C, a display 230D and a keypad 230E. The host computer 230also can include an accelerometer 230F. An operating system 240 canexecute in the memory 230B of the host computer 230 of the mobiletelephone 210. The operating system 240 in turn can support theoperation of a dialer client 250 programmed to provide a computer userinterface to managing the cellular telephone 220. The operating system240 also can support the operation of a messaging client 260, such as atext messenger, instant messenger, e-mail messenger, or any combinationthereof. Finally, the operating system can support the operation of asocial media client 270 through which an end user can post textual,audio and/or visual material to a social network from the mobiletelephone 210.

Notably, the operating system 240 can support the operation of a contactlist management module 280. The module 280 can include program code thatwhen executed by the processor 230A of the host computer 230 can manageone or more contacts in a contact list with which an end user can directthe cellular telephone 220 through the dialer client 250 to initiate atelephone call to the contact. The program code of the module 280additionally, can filter or sort the contacts in the contact list to asubset, for example according to a role fulfilled by the contacts in thesubset. Importantly, the program code of the module 280 can acquireusage data of the mobile telephone 210 in order to computer areachability value for a possessor of the mobile telephone 210. Theusage data can include, by way of example, accelerometer data from theaccelerometer 230F indicating movement of the mobile telephone 210,recency or frequency of use data of the cellular telephone 220, recencyor frequency of use data of the messaging client 260, or recency orfrequency of use data of the social media client 270. Finally, theprogram code of the module 280 can be enabled to retrieve reachabilityvalues for contacts in the contact list so as to sort or filter thecontact list according to contacts determined to be most reachable basedupon the reachability values for each of the contacts in the contactlist.

Optionally, for contacts filtered into a subset according to role, theprogram code of the module 280 can be additionally enabled toautomatically determine a most reachable contact amongst the contacts inthe subset in response to a directive to dial the most reachable contactof the role. Thereafter, the contact determined to be most reachable canbe dialed. To the extent that the contact determined to be mostreachable for the role does not answer the telephone call, a contact ofthe role determined to be the next most reachable for the role can bedialed and so forth until a dialed contact answers the telephone call.In this way, the process of telephoning a person of a specific role canbe made more efficient by ordering dialing attempts by contacts deemedmost reachable.

In even yet further illustration of the operation of the module 280,FIG. 3 is a flow chart illustrating a process for contact listprioritization according to predicted reachability. Beginning in block310, a contact list can be loaded in memory of a host computer, forexample a host computer embedded within a mobile telephone, and in block320, a first contact in the contact list can be selected. In block 330,a reachability value for the contact can be retrieved and applied to thecontact. In decision block 340, if further contacts remain to beprocessed in the contact list the process can repeat through block 320.When no further contacts remain to be processed in the contact list, inblock 350, the contact list can be sorted or filtered according to thereachability values so that the contacts determined to be most reachableaccording to the reachability values can be displayed first in a displayof the host computer.
